IMPORTANT SAFETY INSTRUCTIONS – SAVE THESE INSTRUCTIONS 1.

This manual contains important safety and operating instructions

RISK OF ELECTRIC SHOCK OR FIRE.

Keep out of reach of children.1.1
Do not expose the charger to rain or snow.1.2
Use only recommended attachments. Use of an 1.3

attachment not recommended or sold by Schumacher® Electric

Corporation may result in a risk of re, electric shock or injury

to persons or damage to property.
To reduce the risk of damage to the electric plug or cord, pull by the plug rather than the 1.4

cord when disconnecting the charger.
An extension cord should not be used unless absolutely necessary. Use of an improper 1.5

extension cord could result in a risk of re and electric shock. If an extension cord must

be used, make sure:

That the pins on the plug of the extension cord are the same number, size and shape •
as those of the plug on the charger.

That the extension cord is properly wired and in good electrical condition.•
That the wire size is large enough for the AC ampere rating of the charger as •

specied in section 8.

To reduce the risk of electric shock, unplug the charger from the outlet before attempting 1.6
any maintenance or cleaning. Simply turning off the controls will not reduce this risk.

Do not operate the charger with a damaged cord or plug; have the cord or plug replaced 1.7

immediately by a qualied service person. (Call customer service at: 1-800-621-5485.)

Do not operate the charger if it has received a sharp blow, been dropped or otherwise 1.8

damaged in any way; take it to a qualied service person. (Call customer service at:

1-800-621-5485.)

Do not disassemble the charger; take it to a qualied service person when service or 1.9
repair is required. Incorrect reassembly may result in a risk of re or electric shock. (Call

customer service at: 1-800-621-5485.)

RISK OF EXPLOSIVE GASES.

WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS 1.10
DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING
NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST
IMPORTANCE THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME YOU
USE THE CHARGER.

To reduce the risk of a battery explosion, follow these instructions and those published by 1.11
the battery manufacturer and the manufacturer of any equipment you intend to use in the
vicinity of the battery. Review the cautionary markings on these products and on the engine.

PERSONAL PRECAUTIONS2.

RISK OF EXPLOSIVE GASES.

NEVER smoke or allow a spark or ame in the vicinity of a battery or engine.2.1

Remove personal metal items such as rings, bracelets, necklaces and 2.2
watches when working with a lead-acid battery. A lead-acid battery can produce
a short-circuit current high enough to weld a ring or the like to metal, causing a
severe burn.

Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It might 2.3
spark or short-circuit the battery or other electrical part that may cause an explosion.

Use this charger for charging LEAD-ACID batteries only. It is not intended to supply power 2.4
to a low voltage electrical system other than in a starter-motor application. Do not use
this battery charger for charging dry-cell batteries that are commonly used with home
appliances. These batteries may burst and cause injury to persons and damage to property.

NEVER charge a frozen battery.2.5
NEVER overcharge a battery.2.6
Consider having someone close enough by to come to your aid when you work near a 2.7

lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts your skin, 2.8

clothing or eyes.
Wear complete eye and body protection, including safety goggles and protective 2.9

clothing. Avoid touching your eyes while working near the battery.
If battery acid contacts your skin or clothing, immediately wash the area with soap and 2.10

water. If acid enters your eye, immediately ood the eye with cold running water for at

least 10 minutes and get medical attention right away.
If battery acid is accidentally swallowed, drink milk, the whites of eggs or water. DO NOT 2.11

induce vomiting. Seek medical attention immediately.

PREPARING TO CHARGE3.

RISK OF CONTACT WITH BATTERY ACID. BATTERY ACID
IS A HIGHLY CORROSIVE SULFURIC ACID.

If it is necessary to remove the battery from the vehicle to 3.1

charge it, always remove the grounded terminal rst. Make sure

all of the accessories in the vehicle are off to prevent arcing.

Be sure the area around the battery is well ventilated 3.2

while the battery is being charged.
Clean the battery terminals before charging the battery. During cleaning, keep airborne 3.3

corrosion from coming into contact with your eyes, nose and mouth. Use baking soda
and water to neutralize the battery acid and help eliminate airborne corrosion. Do not
touch your eyes, nose or mouth.

Add distilled water to each cell until the battery acid reaches the level specied by the 3.4
battery manufacturer. Do not overll. For a battery without removable cell caps, such

as valve regulated lead acid batteries (VRLA), carefully follow the manufacturer’s
recharging instructions.

Read, understand and follow all instructions for the charger, battery, vehicle and any 3.5
equipment used near the battery and charger. Study all of the battery manufacturer’s

specic precautions while charging and recommended rates of charge.

Determine the voltage of the battery by referring to the vehicle owner’s manual and 3.6
make sure that the output voltage selector switch is set to the correct voltage. If the

charger has an adjustable charge rate, charge the battery in the lowest rate rst.

Make sure that the charger cable clips make tight connections.3.7

CHARGER LOCATION4.

RISK OF EXPLOSION AND CONTACT WITH
BATTERY ACID.

Locate the charger as far away from the 4.1

battery as the DC cables permit.

Never place the charger directly above 4.2

the battery being charged; gases from the

battery will corrode and damage the charger.
Do not set the battery on top of the charger.4.3

Never allow battery acid to drip onto the charger when reading the electrolyte specic 4.4
gravity or lling the battery.

Do not operate the charger in a closed-in area or restrict the ventilation in any way.4.5

DC CONNECTION PRECAUTIONS5.

Connect and disconnect the DC output clips only after setting all of the charger switches 5.1
to the “off” position (if applicable) and removing the AC plug from the electrical outlet.
Never allow the clips to touch each other.

Attach the clips to the battery and chassis, as indicated in sections 6 and 7.5.2

FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE6.

A SPARK NEAR THE BATTERY MAY CAUSE
A BATTERY EXPLOSION. TO REDUCE THE
RISK OF A SPARK NEAR THE BATTERY:

Position the AC and DC cables to 6.1
reduce the risk of damage by the hood, door
and moving or hot engine parts. NOTE: If
it is necessary to close the hood during the

charging process, ensure that the hood does not touch the metal part of the battery clips
or cut the insulation of the cables.

Stay clear of fan blades, belts, pulleys and other parts that can cause injury.6.2
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post usually 6.3

has a larger diameter then the NEGATIVE (NEG, N, -) post.
Determine which post of the battery is grounded (connected) to the chassis. If the 6.4

negative post is grounded to the chassis (as in most vehicles), see step 6.5. If the
positive post is grounded to the chassis, see step 6.6.

For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the battery 6.5
charger to the POSITIVE (POS, P, +) ungrounded post of the battery. Connect the
NEGATIVE (BLACK) clip to the vehicle chassis or engine block away from the battery.
Do not connect the clip to the carburetor, fuel lines or sheet-metal body parts. Connect
to a heavy gauge metal part of the frame or engine block.

For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the battery 6.6
charger to the NEGATIVE (NEG, N, -) ungrounded post of the battery. Connect the
POSITIVE (RED) clip to the vehicle chassis or engine block away from the battery. Do
not connect the clip to the carburetor, fuel lines or sheet-metal body parts. Connect to a
heavy gauge metal part of the frame or engine block.

Connect charger AC supply cord to electrical outlet.6.7
When disconnecting the charger, turn all switches to off, disconnect the AC cord, remove 6.8

the clip from the vehicle chassis and then remove the clip from the battery terminal.
See CALCULATING CHARGE TIME for length of charge information.6.9
